The LOFAR Tied Array All-sky Survey (lotaas) published its results in 2018 and 2019 with a total of 53 new pulsars discovered. It detected a grand total of 317 pulsars. The fastest pulsar discovered was J0827+53 with a period of 13.5 milliseconds and the slowest pulsar was J0250+5854 with a period of 23.53538 seconds.
The smallest pulsar dispersion measure was J1658+3630 with a DM of 3.04387 pc/cc and the largest pulsar dispersion measure was J2006+22 with a DM of 130.56 pc/cc. There were a total of 2639 pulsars known before the first discovery was published. This survey increased the total amount of known pulsars by 2.0%.
